The Showtime Original Series DEXTER™ is back with an all-new season, and this time America's favorite serial killer has gone from freewheeling bachelor to responsible husband and doting dad. Maintaining an average-guy facade while satisfying his need to kill has never been easy. But now, with wife and kids in tow, Dexter's got more to lose then ever, as he gets drawn into a deadly game with a killer every bit as dangerous — and conflicted — as he is.

Unfolding with tragic inevitability, Dexter's fourth season is a taut game of cat and mouse between Dexter (Emmy nominee Michael C. Hall) and Arthur Mitchell, "a very special kind of monster," unnervingly portrayed by John Lithgow in his Emmy and Golden Globe-winning performance. Whoever guest stars in seasons to come has a very hard act to follow. (Never mind all the blood, Mitchell's greeting, "Hello, Dexter Morgan," from the episode of the same name, will disturb your sleep.) But let's not forget Hall's consistently cutting-edge work. The Dexter saga has a rich back-story and mythology, but for those new to the series and lured to this season by Lithgow's justly celebrated performance, season 4 is a good place to start, because it represents something of a new beginning for Dexter himself. Married at the end of season 3, he is now dreaming of "having it all" as a husband and father, trying to juggle the demands of his job as a Miami Metro Police Department blood-spatter analyst, his new family, and his other calling as a serial killer. But he is more conflicted than ever. His new baby keeps him up nights, and the normally precise and methodical Dexter finds himself exhausted to the point of making mistakes in court. "Who knew life could get so unsimple?" he asks early on. Dexter and Mitchell are not the only characters harboring secrets. Some we can mention (Lieutenant Maria LaGuerta and Detective Angel Batista are in a relationship), but others we dare not even hint at (the episode "Hungry Man" has a doozy of a cliffhanger revelation). As the season unfolds, an incognito Dexter insinuates himself into Arthur's life and discovers disturbing parallels in their lives. Meanwhile, now-retired serial killer hunter Frank Lundy (Keith Carradine), who nearly uncovered Dexter's identity back in season 2, returns to ask for his help in catching the Trinity Killer. His reappearance upends the life of Dexter's sister Debra (Jennifer Carpenter), a homicide detective and Lundy's former lover. Debra has also been digging into the past of her late policeman father Harry (James Remar) and learns more about her twisted family tree. Disappointingly, interviews with Hall, Lithgow, and other cast members can be accessed only on a PC, but the DVD does contain episodes of Californication, Lock 'N Load, and The Tudors. --Donald Liebenson

NCIS (Naval Criminal Investigative Service) is more than just an action drama. With liberal doses of humor, it's a show that focuses on the sometimes complex and always amusing dynamics of a team of special agents forced to work together in high-stress situations. From murder and espionage to terrorism and stolen submarines, these special agents travel the globe to investigate all crimes with Navy or Marine Corps ties.

"A few months ago, I had not even heard of NCIS," a terrorist remarks in the gripping season opener, "Truth or Consequences," a benchmark episode. Where's he been? NCIS was television's top-rated scripted drama, an impressive achievement for a show in its seventh season. NCIS may not have any Emmys to its credit or generate water cooler buzz, but it's got a devoted fan base who will follow Special Agent Gibbs (Mark Harmon) and the rest of the Naval Criminal Investigative Service wherever their investigations take them. In the brilliantly constructed and executed "Truth or Consequences," it's North Africa, where movie-referencing hunk Special Agent DiNozzo (Michael Weatherly) and McGee (Sean Murray) have been captured while investigating Ziva's disappearance. For uninitiated "probies," this episode serves as a series primer as DiNozzo, tied to a chair and shot up with sodium pentothal, gives a rundown to his captor about the rest of the team and their standing in the NCIS universe. There is considerable comfort to be taken in the show's format. Episodes usually begin with discovery of a shocking and grisly murder, then office banter and byplay until Gibbs announces said crime ("We got a dead marine, grab your gear") and then the labyrinthine investigation leading to an act 4 twist. This isn't Law and Order, where sometimes the guilty walk. This is NCIS and justice is always served. But it's not the crimes; it's the characters that are at the heart of this series' enduring popularity. This season provides Ziva (Cote de Pablo) with an especially satisfying arc as she quits the Mossad to become an actual NCIS agent and studies for her United States citizenship exam. Her will they-won't they romantic tension with DiNozzo simmers satisfactorily over the course of the season. Season 7 comes full circle with Gibbs's capture by Mexican drug cartel leader Paloma Reynosa, seeking revenge for Gibbs's murder of her father. She offers him a career change. "You might as well put a bullet in my head," Gibbs predictably replies. But she ups the ante in an unspeakably bad way that is the stuff season-ending cliffhangers are made of. This DVD contains interesting special features that immerse viewers in the production of the series, from the sound design to the design of Gibbs's house, which is seen for the first time this season. --Donald Liebenson

Get the ultimate Iron Man 2 experience with this special edition loaded with bonus features that take you inside the suit, plus a digital copy of the film that you can watch anywhere, anytime! Now that Tony Stark’s superhero secret is revealed to the world, he must once again suit up in order to face his most dangerous enemy yet – but not without a few new allies of his own!

Amazon.com 

After the high-flying adventures of the first Iron Man picture, the billionaire arms manufacturer and irrepressible bon vivant Tony Stark (Robert Downey Jr.) finds himself nursing a hangover. But not like any hangover he's had before: this one is toxic, a potentially deadly condition resulting from heavy metals (or something) bleeding out of the hardware he's installed in the middle of his chest. This is the problem Stark needs to solve in Iron Man 2, not to mention the threat from resentful Russian science whiz Ivan Vanko (Mickey Rourke), whose father helped create the Iron Man technology. There's an even bigger problem for the film: the need to set up a future Marvel Comics movie universe in which a variety of veteran characters will join forces, a requirement that slows down whatever through-line the movie can generate (although fanboys will have a good time digging the clues laid out here). Actually, the main plot is no great shakes: another Iron Man suit is deployed (Don Cheadle, replacing Terrence Howard from the first film, gets to climb inside), Stark continues to bicker with assistant Pepper Potts (Gwyneth Paltrow), and a weaselly business rival (Sam Rockwell) tries to out-do the Iron Man suit with an army of Vanko-designed drones. Mickey Rourke is a letdown, burdened by a wobbly Russian accent and looking skeptical about the genre foolishness around him, and Scarlett Johansson has to wait until the final couple of reels to unleash some butt-kickin' skills as the future Black Widow. That climax is sufficiently lively, and the initial half-hour, including Stark's smirky appearance before a Senate committee and a wacky showdown at the Monaco Grand Prix, provides a strong, swift opening. But the lull between these high points is crying for more action and more Downey improv. --Robert Horton

About Zumba Fitness
Celebrity fitness trainer "Beto" Perez stumbled upon the concept of Latin-inspired dance fitness in his native Cali, Colombia, in the mid-'90s. One day, he walked into his aerobics class and realized he had forgotten his aerobics music. Thinking quickly, he grabbed some tapes from his backpack, which included the traditional Latin salsa and merengue music he'd listened to all his life. Although it was tough to improvise a whole class on the spot, Beto rose to the challenge and gave birth to a revolutionary new concept in fitness: the Zumba Fitness Party. The class soon became the most popular class at his fitness facility. As of July 2009, the Zumba program is being taught at more than 50,000 locations in 75 countries, has sold millions of DVDs, and has changed the lives of Zumba fanatics worldwide, with an estimated 6 million participants taking Zumba classes every week.

In addition to the 12 DVD workouts, the P90X comes with a comprehensive three-phase nutrition plan, specially designed supplement options, a detailed fitness guide packed with valuable information on how to get the most from your program, a How to Bring It DVD that provides a quick overview of the system, a calendar to track your progress, online peer support, and much more.

The DVD Workouts
Each of the 12 highly diverse and intense DVD workouts focuses on either a specific set of muscle groups or a unique training technique.

• Workout One: Chest & Back. This superset chest-and-back-blasting workout emphasizes two classic upper-body exercises--push-ups and pull-ups--to build strength and develop shape. The combination of these two push and pull movements will help you burn loads of calories while simultaneously attacking, strengthening, and developing multiple muscle groups.

• Workout Two: Plyometrics. Get ready to go airborne. Offering more 30 explosive jumping moves, this intense cardio routine will keep you in the air most of the time. Plyometrics, also known as jump training, has been proven to dramatically improve athletic performance. If your sport involves a ring, rink, field, court, or track, this training will give you the edge. Just be prepared to "bring it" for a full hour when you leap into this workout, because there is no letting up.

• Workout Three: Shoulders & Arms. Nothing rounds out the perfect physique like a pair of well-defined arms and shoulders, and with its potent combination of pressing, curling, and fly movements, this routine will leave you feeling stronger and looking sexier. Whether you want to build muscle mass or just slim and tighten what you've already got, these targeted shoulder and arm exercises will give you the results you want.

• Workout Four: Yoga X. Yoga is a vital part of any fitness regimen, and is an absolute must for an extreme program like P90X. This routine combines strength, balance, coordination, flexibility, and breath work to enhance your physique and calm your mind. Yoga X will leave you feeling energized, invigorated, and maybe even a little enlightened.

• Workout Five: Legs & Back. Get ready to squat, lunge, and pull for a total-body workout like no other. While the main focus of this workout lies in strengthening and developing the leg muscles (quads, hamstrings, glutes, and calves), there are also a handful of great pull-up exercises to give your legs a quick breather while you work the upper body.

• Workout Six: Kenpo X. Kenpo X was created to give P90X users a high-intensity cardiovascular workout packed with lots of punching and kicking combinations to improve balance, endurance, flexibility, and coordination. During this workout you'll learn some of the most effective ways to defend yourself, while at the same time getting your body in peak condition.

• Workout Seven: X Stretch. Stretching is the one thing that will help you achieve a higher level of athleticism over a longer period of time. The X Stretch routine is an integral part of the program, as it helps prevent injuries and avoid plateaus. The extensive full-body stretches that make up this routine use disciplines from Kenpo karate, hatha yoga, and various sports to ensure that your body is fully prepared to meet all P90X challenges head-on.

• Workout Eight: Core Synergistics. Each and every exercise in the Core Synergistics workout recruits multiple muscle groups to build and support the core (lumbar spine and trunk muscles), while at the same time conditioning your body from head to toe. Loaded with a variety of fun, unique, and challenging exercises, this routine will get you moving in all directions to maximize your P90X results.

• Workout Nine: Chest, Shoulders, & Triceps. Packed with an array of moves that target both large and small muscles, this workout will do wonders for your upper body. In just one full sequence you'll get a healthy dose of presses, flys, and extensions to push you to the brink. The results will be a stronger, leaner, and highly defined upper torso that will leave you looking awesome, with or without a shirt.

• Workout 10: Back & Biceps. With a host of curls and pull-ups, this routine will make it fun to flex those powerful biceps. But don't worry, ladies--by using lighter weight, you can focus on toning and tightening these showcase arm muscles without adding the size that most guys covet. Additionally, this workout also provides some great back definition that everyone can appreciate. Regardless of your goals, you will achieve them in dramatic fashion if you dig in and max out your reps.

• Workout 11: Cardio X. This low-impact cardio routine can be used in a variety of ways to meet your P90X goals. Use it in addition to your standard P90X workload when you want to burn some extra calories, or as a substitute if your body needs a break from the program's high-impact workouts. Whatever your reason for using Cardio X, you'll find it a fun, full-throttle, fat-burning workout that will leave you feeling lean and mean.

• Workout 12: Ab Ripper X. The combination and sequence of movements in this unique workout taps into not only abdominal strength, but true core strength as well. Master these 11 highly effective exercises and you will achieve vital abdominal muscle strength to benefit your overall health and physical performance. You'll also develop that highly coveted six-pack as you take Ab Ripper X to full throttle. It's extreme work that's better than any machine in any club.
